What is the purpose of the collation selection in the installation screen?

The collation option determines the way ordering in the database is done. In languages that use special characters, for instance the German umlaut, the database collation determines the sorting order. If you don't know which collation you need, select the "utf8_general_ci" as most languages use this. The other collations listed are exceptions in regards to the general collation. If your language is not listed in the list of collations it most likely means that "utf8_general_ci is suitable.

Platforms and Open Standards

Joomla! runs on any platform including Windows, most flavours of Linux, several Unix versions, and the Apple OS/X platform. Joomla! depends on PHP and the MySQL database to deliver dynamic content.

The minimum requirements are:

• Apache 1.x, 2.x and higher
• PHP 4.3 and higher
• MySQL 3.23 and higher

It will also run on alternative server platforms such as Windows IIS - provided they support PHP and MySQL - but these require additional configuration in order for the Joomla! core package to be successful installed and operated.

What is the difference between Archiving and Trashing an Article?

When you Archive an Article, the content is put into a state which removes it from your site as published content. The Article is still available from within the Control Panel and can be retrieved for editing or republishing purposes. Trashed Articles are just one step from being permanently deleted but are still available until you Remove them from the Trash Manager. You should use Archive if you consider an Article important, but not current. Trash should be used when you want to delete the content entirely from your site and from future search results.
